From: Estimating tie strength in social networks using temporal communication data
Composition of weekly call profiles of social ties and their association with the neighbourhood overlap. Each bin represents an hour of the week (x-axis: hours, y-axis: days), and the number inside the bin is the corresponding cluster index. The bin’s color indicates the level of Pearson’s correlation of each tie’s fraction of events in the bin’s cluster with the overlap. E.g., a tie’s topological overlap correlates positively with the fraction of calls across that tie that take place between noon and 4 PM on weekends
